Industrial-grade Magnesium Hydroxide Manufacturer Wholesale

Industrial-grade magnesium hydroxide is a white, odorless, non-toxic and halogen-free hexagonal crystal or amorphous powder with a density of approximately 2.36g /cm³. It is chemically stable at normal temperature and almost insoluble in water (with a solubility of only 0.0009g /100g at 20℃). Its aqueous solution is weakly alkaline (pH≈9.5-10.5), and it belongs to the environmentally friendly type of medium to strong alkali. Magnesium hydroxide decomposes into magnesium oxide and water at high temperatures ranging from 340℃ to 350℃. This process can absorb a large amount of heat, release water vapor to dilute oxygen, and endow it with excellent flame retardant, smoke suppression and filling functions. It is an ideal additive in fields such as plastics, rubber, and environmental water treatment.

Customized service: We can provide customized products with different particle size distributions, surface activation treatments and purity grades based on your application requirements.

Application field

The field of flame-retardant materials

• Engineering plastics: Applicable to high-temperature processing engineering plastics such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and nylon (PA), effectively replacing aluminum hydroxide (due to its higher decomposition temperature).
• Rubber and cables: Used for cable sheaths, mining conveyor belts, insulating materials, enhancing flame retardancy and reducing smoke generation.
• Building materials and coatings: Added to fireproof coatings and fireproof boards, it forms a magnesium oxide insulation layer when heated, delaying the spread of fire.

The field of environmental protection treatment

• Acidic wastewater neutralization: Replace caustic soda/lime, used in electroplating and chemical wastewater treatment, avoiding sudden pH rise, mild and easy to control reaction.
• Heavy metal removal: Through surface adsorption and precipitation, heavy metal ions such as Pb²⁺, Cu²⁺, and Cr³⁺ in wastewater are effectively removed.
• Flue gas desulfurization: Magnesium hydroxide slurry efficiently absorbs SO₂, generating magnesium sulfate as a by-product, achieving resource utilization.

Other industrial applications

• Chemical raw materials: As a precursor, used for the production of high-purity magnesium oxide, electrical grade magnesium oxide and other magnesium salts.
• Oil additives: Added to lubricating oil/fuel oil, they play a role in anti-corrosion and desulfurization.
• Agriculture and medicine: Used for soil pH regulation (replacing lime), magnesium fertilizer supplementation; High-purity grade can also be used in pharmaceutical preparations.

Packaging and storage and transportation

• Packaging specifications:Standard packaging: 25kg per bag (composite paper bag lined with polyethylene film).Customization support: We offer a variety of specifications ranging from 1kg sample bags to 1000kg ton bags.
• Storage conditions: Keep in a cool, dry and well-ventilated place, sealed and protected from moisture.
• • Transportation requirements: Non-hazardous goods. Handle with care. Avoid mixed transportation with acidic or alkaline substances.
